When you say sewer and refer to the shower pipe, the shower pipe is part of the building drain. The Sewer is outside of the building and connects to the street or a Septic Tank. You can also help by explaining with a photo so we can understand your problem. Take a photo and post your question again.

yes the shower is connect to the main drain line and the main drain line runs to the septic tank which the kitchen sink on as well.One long pipe from the toilet, shower, washer, sink, septic tank.
